Disclosed herein is a catalyst for particulate combustion which is essentially free of platinum group metal compounds and the catalyst comprises a carrier and at least one metal oxide chosen from iron oxide and manganese oxide, and combinations thereof.

The present disclosure provides a method for preparing a selective catalytic reduction (SCR) catalyst, the SCR catalyst comprises a metal ion-exchanged zeolite. A method uses an in-situ ion exchange process. A process includes admixing a zeolite in the ammonium (NH.sub.4.sup.+) form with an aqueous mixture comprising water, a transition metal ion source, and, optionally, an acid, to form a slurry containing a metal ion-exchanged zeolite.

The process comprises hydrocracking a hydrocarbon feed in a single stage. The catalyst comprises a base impregnated with metals from Group 6 and Groups 8 through 10 of the Periodic Table. The base of the catalyst used in the present hydrocracking process comprises alumina, an amorphous silica-alumina (ASA) material, a USY zeolite, optionally a beta zeolite, and zeolite ZSM-12.

A Nitrogen Oxide (NOx) sorbent material of the present invention includes a multi-metallic oxide that includes one or more alkali or alkaline earth metal, one or more 3d transition metal, and one or more rare earth element. The NOx sorbent material is configured to adsorb and absorb NOx below a low temperature and to release the adsorbed or absorbed NOx at temperature at or above the low temperature. In some embodiments, a manganese catalyst is deposited on a high surface area carrier. The manganese catalyst takes the form of an alkali/metal promotor and an Mn-based compound. In general, the NOx sorbent material contains about one percent to about fifty percent by weight of alkali/alkaline earth metal manganese catalyst based on the total weight of the catalyst.

The present invention relates to a metal oxide coated composite comprising a core consisting of a mixture of a La stabilised AI.sub.2O.sub.3 phase and an Ce/Zr/RE.sub.2O.sub.3 mixed oxide phase, the core having a specific crystallinity, specific pore volume and a specific pore size distribution, and a method for the production of the metal oxide coated composite.

A NO.sub.x adsorber catalyst and its use in an emission treatment system for internal combustion engines, is disclosed. The NO.sub.x adsorber catalyst comprises a first layer consisting essentially of a support material, one or more platinum group metals disposed on the support material, and a NO.sub.x storage material.

A method of dry reforming of methane (CH.sub.4) is provided. The method includes contacting at a temperature of 500 to 1000 degree Celsius (° C.) a reactant gas mixture including methane and carbon dioxide (CO.sub.2) with a bimetallic supported catalyst. The bimetallic supported catalyst includes a porous catalyst support and a bimetallic catalyst. The porous catalyst support includes aluminum oxide (Al.sub.2O.sub.3) and magnesium oxide (MgO). The bimetallic catalyst includes nickel (Ni) and copper (Cu) disposed on the porous catalyst support. The method further includes collecting a product gas mixture including hydrogen (H.sub.2) and carbon monoxide (CO). The bimetallic supported catalyst includes 8 to 16 weight percent (wt. %) nickel and 2 to 14 wt. % copper, each based on a total weight of bimetallic supported catalyst.

A new catalyst hydroisomerizes C18 paraffins from fatty acids to a high degree to produce a composition with acceptable freeze point which retains 18 carbon atoms in the hydrocarbon molecule for jet fuel. We have discovered a fuel composition comprising at least 14 wt % hydrocarbon molecules having at least 18 carbon atoms and a freeze point not higher than −40° C. The composition also may exhibit a exhibiting a final boiling point of no more than 300° C. The hydroisomerization process can be once through or a portion of the product diesel stream may be selectively hydrocracked or recycled to hydroisomerization to obtain a fuel composition that meets jet fuel specifications.

Provided is a structured catalyst for hydrodesulfurization that suppresses the decline in catalytic activity and achieves efficient hydrodesulfurization. The structured catalyst for hydrodesulfurization (1) includes a support (10) of a porous structure composed of a zeolite-type compound, and at least one catalytic substance (20) present in the support (10), the support (10) having channels (11) connecting with each other, and the catalytic substance (20) being present at least in the channels (11) of the support (10).

A double-layer structured catalyst for use in dehydrogenation of light hydrocarbon gas within a range of C3 to C6, configured such that platinum, tin, and an alkali metal are carried in a phase-changed carrier, wherein the tin component is present in an entire region inside the carrier, and the platinum and the tin form a single complex and are present in an alloy form within a range of a predetermined thickness from an outer periphery of the carrier.
